Absolute Boyfriend (Manga)
Absolute Boyfriend by Yuu Watase was released in March 2003 and ran into February 2005. Consisting of 6 volumes which were released by Viz Media in the North American Market. (Which I currently own) Spawning a live action series in Japan back 2008. A Taiwanese version released in 2012. And their also a rumored South Korean Version on the way.
This story follows Riiko Izawa and her growing relationship with her nightly lover doll Knight. And also her budding relationship with her friend/neighbor Soushi Asamoto; the prince she never realized she had. Riiko accidentally ordered, Night from a company called Kronos Heaven whom over the course of the series are a constant problem for the 16 year old.
Likable characters. A LEGIT love triangle was built. I genuinely felt bad for Riiko. I would also like to add, I laughed alot. This was one of my first manga, so I highly recommend this. Night Doe!
